I will start off with specs: Asus motherboard, 1.2 AMD Duron, ATI video card(256 megs) 512 ram, 60 gig hard drive It started off giving me problems one day with no video or beeps. I disconnected everything but the cpu and got the beeps for no ram. I did have a 512 and 256 ram installed, but it would only work with the 512 after I reinstalled it and it worked for a while. I recently bought a new CPU fan because my last one was falling apart. I got my new one and added the grease stuff and once again got nothing. I tried removing it all again and now I get nothing, even when I remove the memory, it won't beep now. The fans come on fine, but I can't get a beep nor video. I also tried removing the cmos battery to reset it, but I get nothing.
